To all people using Mull, the privacy hardened variant of Firefox for Android:
The F-Droid version is very slow on updates. The cycles are about 1 per month or less.
DivestOS maintains Mull, and they have their own repo (above link).
Add their repo and get Mull from there.
If you already have it installed from F-Droid, you need to reinstall it, as the app comes from different developers so the Keys dont match.
If you are on GrapheneOS, Vanadium is the most secure browser and allows very well integrated process isolation.
Brave is similar but less secure, has better privacy features but also a ton of controversial stuff and (at least in the past) a really bad CEO.
Mull is likely most privacy hardened, interoperable with Firefox and has Addon support. But until there are other infos it has to be assumed as less secure.
Obtainium users
I use Obtainium.
For practicality I also have F-Droid Basic installed.
Add the repo in F-Droid basic, and search for Mull. If you are on the app page, use the “send” feature.
Your link will contain the exact name of the app.
In Obtainium, enter the URL of the repo at the top, then select “F-Droid 3rd party repo” as type and in “app id” enter the app name.

DivestOS makes Mull, F-Droid waiting is just their inability to view into their processes. I dont think there is any form of review included, between upgrades.
I still am not going to add extra repos.
You use code made by another project. They have their own repo.
